CHARLES LEWIS BENEDICT, OF TORONTO, ONTARIO, CANADA.

LOOSE-LEAF BINDER.

To all whom it may concern:

Be it known that I, CHARLES Lnwrs BENE- DICT, a subject of the King of Great Britain, resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Loose-Leaf Binders, of which the following is a specification.

The invention relates to improvements in loose leaf binders, as described in the present specification and illustrated by the accompanying drawings that form part of the same.

The invention consists in the novel construction and arrangement of parts, whereby one of the binder covers is pivotally arranged to swing in a substantially parallel plane to the other cover and is lockec in its closed position.

The objects of the invention are to remove and replace the leaves with despatch, to obviate the troubles incident to the ordinary displacement of the upper cover in known methods, and to facilitate the accessibility of the letters contained in the file or binder.

In the drawings, Figure 1 is a perspective view of the binder with the upper cover adapted to swing over the lower cover and showing the said cover in its closed and locked position. Fig. 2 is a reduced perspective view of the binder with the upper cover swung out to its open position. Fig. 3 is an enlarged perspective detail of a portion of the binder bar of the upper cover showing the means for locking the said cover to its closed position. Fig. 4 is an enlarged perspective detail of a portion of the binder bar of the u er cover showing .a modified form of tile ocking means.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the bottom or base board of the binder, preferably haviglg a metal end bar 2 or metal covered end 3 is a post rigid with said end bar 2 and extending upwardly therefrom in proximity to one end thereof and forming a pivot post.

4 are posts extending upwardly from the bar 1 and rigid therewith and forming the posts on which the loose leaves are filed.

5 is the cover having at one end thereof the metal or metal covered binder bar 6, the said bar having slots 7 extending inwardly from its outer side and adapted to receive the posts 4.

8 is a hole through the binder bar 6 in prox- Specification of Letters Patent.

Application filed July 15, 1907.

Patented Dec. 8, 1908.

Serial No. 383,932.

imity to one end thereof and 9 is a bushin extending through said hole and therebeyon and in its inner dimensions corresponding to and vertically sliding and rotatmg on the post 3.

10 are wires having their inner ends firmly embedded in the metal binder bar 6 to the rear of the slots 7 and formed into the narrow neck loop 11. The loop 11 is formed to partially encircle the posts 4 in the closed position of the cover 5, the said posts having first to pass through the narrow neck into said loops.

The loops 11 are formed of spring wire, so that on closing the cover 5, if sufficient pressure is brought to bear, the necks of said loops are made to pass by said posts 4 bringing said posts 4 into the loops and effectually locking them there, until such time as sufficient pressure is brought to bear in the other direction to open said cover. The cover 5 swings on the pivot 0st 3 and will always remain in substantial y a parallel plane with the bottom or base board, as the said elongated bushing 9, extending through the binder bar 6 and therebeyond, holds the said cover rigidly in its horizontal position, when relieved from engagement with the posts 4 and the loose leaves therebeneath.

12 is a knob rojecting upwardly from the binder bar 6 and rigid therewith in proximity to the end opposite to the pivoted end, and is used to facilitate the swinging of said cover 5 and thus do away with much of the handling thereof and consequent wear.

In Fig. 4 I have shown a modified form of locking mechanism in which it will be seen that the release of the cover from the posts 4 must be obtained through the use of a key and this form may be used in conjunction with the spring wires 10, if so desired.

In the locking mechanism shown in Fig. 4, 13 is a bolt slidably arranged on the bar 6, and retained in position by the straps 14 rigidly secured to said plate and extending over said bolt.

The posts 4 are formed with a plurality of horizontal notches arranged vertically throughout the length thereof and the bolt 13 is ada ted to slide thereinto and thus securely ho d the said bar 6 and cover 5 se curely from vertical or lateral movement.

The bolt 13 may be operated by any suitable form of key.

While one form of key lock is herein shown and described, many forms may be used to A binder such as described is very conven ient and easily handled and papers may be filed thereon or removed therefrom without the necessity of removing the cover it being merely necessary to rel-ease the same from engagement with the posts 4 and swing it out of the way.

It must be understood, that while I have confined this description to the most convenient form of construction, that is, with the binder bars at one end of the cover and base board and the slots in said binder bar and the hole therethrough encircling the pivot post, that without departing from the spirit of my invention, I may adopt other means of fastening than shown and described and other means of pivoting the cover to swing in a plane, substantially, horizontal with the base board.

What I claim as my invention is 1 A loose leaf binder, comprising, an under binder cover, posts rigidly secured to said cover at one end and extending upwardly therefrom, and an upper binder cover having a binder bar at one end thereof, said binder bar being rigid from end to end and pivotally supported from one of said posts and swinging thereon from and to the other of said posts in a plane parallel to said under cover.

2; In a loose leaf binder, in combination, an under binder cover, a plurality of posts rigidly secured to and extending upwardly from said under binder cover, a top binder cover having a rigid binder bar pivotally supported from one of said posts and held in a plane substantially parallel with said under cover and adapted to swing on its pivot from and to the side of the other of said posts, and means secured to said binder bar for locking the outer edge thereof against the sides of said posts, substantially as described.

3. In a loose leaf binder, the combination with an under binder cover and a plurality of posts rigidly secured thereto and projecting vertically therefrom, of a slotted top cover having a corner hole arranged therein, and a sleeve journaled on oneof said posts and rigidly secured in the corner hole in said top cover and adapted to permit a lateral swing to said top cover from and to the other of said posts, said slots in said top cover registering with said other posts, substantially as described.

4. In a loose leaf binder, the combination with an under cover, corner posts rigidly secured thereto and projecting therefrom and an intermediate post between said corner posts, of a top cover having a corner hole and slots extending inwardly in the back piece thereof, a sleeve journaled on one of said corner posts and firmly secured to said top cover in said corner hole and permitting said top cover to swing laterally from and to the other of said posts, and means associated with said top cover adjoining said slots for locking said top cover to the other of said posts, substantially as described.

5. In a loose leaf binder, in combination, a bottom or base board having a binder bar at one end thereof, a post rigid with said binder bar and extending upwardly therefrom at one end thereof and forming a pivot, a plurality of posts rigid with said binder bar and extending upwardly therefrom and adapted to receive the loose leaves thereon, a cover having a binder bar at one end thereof, said bar having an orifice through one end thereof and surrounding said pivot post and a plurality of slots from the outer edge thereof adapted to close on said binder posts, and means secured to said bar for locking said cover to said binder posts, substantially as described.

6. In a loose leaf binder, in combination, a bottom or base board having a binder bar at one end thereof, a post rigid with said binder bar and projecting upwardly therefrom and forming a pivot, a plurality of posts projecting upwardly from said binder bar and adapted to receive the loose leaves thereon, a cover having a binder bar at one end thereof, said bar having a hole in proximity to one end thereof and a plurality of slots from the outer edge thereof adapted to close on said posts, a bushing encircling said pivot post and rigidly secured in said hole in said binder bar in the cover, and spring wires secured to said binder bar of the cover to the rear of said slots and formed into narrow necked loops over said slots and partially encircling said loose leaf posts in the closed position of said cover, substantially as described.

7. In a loose leaf binder, a bottom or base board having suitable posts projecting upwardly from one end thereof, a cover having a binder bar at one end thereof, said bar having a pluralit of slots from the outer edge adapted to cfbse on said posts and spring wires secured to said binder bar of the cover to the rear of said slots and extending forwardly and formed into narrow necked loops over said slots and partially encircling said posts in the closed position of said cover, substantially as described.
